The 27th Canadian Parliament was in session from December 9, 1965 until April 23, 1968. The membership was set by the 1965 federal election on November 8, 1965, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1968 election.

It was controlled by a Liberal Party minority under Prime Minister Lester B. Pearson and the 19th Canadian Ministry. Pierre Trudeau succeeded Pearson as party leader and Prime Minister shortly before this Parliament ended for the 1968 national election.

The Official Opposition was the Progressive Conservative Party, led first by John Diefenbaker, and subsequently by Michael Starr.

The Speaker was Lucien Lamoureux. See also List of Canadian electoral districts 1952-1966 for a list of the ridings in this parliament.

There were two sessions of the 27th Parliament.

Most of the MPs were elected as the single member for their district. Two represented Queen's (PEI) and two represented Halifax.
